Silicon Based Planar Millimeter-wave Antennas on Chip for Miniaturized Radar Applications

To study the integration trend of miniaturized antennas for modern wireless applications, the state-of-the-art design approaches of the silicon based millimeter-wave antenna-on-chip (AoC) are overviewed. From integration aspect, "monolithic versus hybrid" concept is compared and discussed with pros and cons. Silicon based monolithic millimeter-wave integrated circuits (SIMMWIC) technology is introduced as one of the reliable candidates of the monolithic solution. The rectifying antenna implemented in SIMMWIC technology is taken as an example for monolithic AoC application. The monolithic IMPATT transmitter is introduced to demonstrate the 3D EM design and verification of AoC performance. Both the challenges and solutions for silicon based millimeterwave AoC design are discussed each from simulation and measurement aspect, which offers a solid base for miniaturized radar system solution.
